title: Cystic fibrosis. An overview.
abstract: A single gene defect in cystic fibrosis results in a spectrum of clinical presentations. Though expression is variable, the radiographic appearance reflects the underlying pathophysiology. Abnormalities of the small airways result in air-trapping; bronchiectasis and mucus plugging reflect large airway disease. These radiographic findings can be assessed and followed using varying scoring systems.
